Black Level Uplift
Overlapping edges may appear lighter than the rest
of the image. Counteract this effect by raising black
levels in the rest of the image. The amount of uplift
required will be either x2 or x4, depending on how
many images are overlapped.
The following example shows a segment with
overlapping edges on all sides.
5
Unblended Region
This region is not overlapped. Black level
should be raised by the maximum overlap
occurring within the segment, therefore
Black Level Uplift
should be x4.
6
Upper Middle
This section of the image is overlapped
by two projectors, therefore the correct
amount of
Black Level Uplift
should be
x2.
7
Upper Right
This part of the image is overlapped by
four projectors, therefore
Black Level
Uplift
should not be applied.
